Jim Denevan [link] is a chef from california, USA, but not all of his handy work fits easily onto a plate. Denevan also creates huge freehand sand drawings using a combination of tools and a truck. one of his more recent pieces has been dubbed the 'largest freehand drawing in the world' and it certainly is big at 3 miles (4.8km) across! the circular work took 100 (160km) miles / eight days of walking to complete and was washed away in a rainstorm the next week. more info and images on the piece can be found over at dark roasted blend.
